摘要:
In a radiographic image capturing apparatus, a biopsy region positional information calculator calculates a three-dimensional position of a biopsy region in an object to be examined based on two radiographic images which are acquired in a stereographic image capturing process, an irradiated field calculator calculates a new irradiated field covering the biopsy region based on the calculated three-dimensional position of the biopsy region and two angles at which a radiation source is disposed in the stereographic image capturing process, and a collimator controller controls a collimator to change the irradiated field of the radiation to the new irradiated field in a next stereographic image capturing process.
